> Toxicology Excellence for Risk Assessment (TERA) is conducting a peer
> consultation on June 29, 2004 in Cincinnati Ohio to discuss a 
> harmonized
> physiologically-based pharmacokinetic (PBPK) model for 
> trichloroethylene
> (TCE).  A panel of experts in PBPK modeling and TCE kinetics and
> metabolism will meet for the purposes of soliciting expert advice on 
> how
> to improve the draft model.  TERA, a non-profit organization, is
> convening this meeting, which will be open to the public.  More
> information on the peer consultation will be available shortly at
> http://www.tera.org/vera/TCE%20announcement.htm.
>
> Background
>
> Currently, there is no single PBPK model that incorporates the full
> range of available science and data on the pharmacokinetics of TCE and
> its metabolites.  Scientific teams led by Dr. Jeffrey Fisher and Mr.
> Harvey Clewell have each developed one or more PBPK models for TCE and
> its metabolites.  These models have different structures both in terms
> of their tissue compartments as well as in their metabolic pathways and
> are based on largely independent data sets.
>
> The U.S. Air Force (USAF) and the U.S. Environmental Protection Agency
> (EPA) are jointly sponsoring a scientific workgroup to develop a
> harmonized PBPK model for TCE and its metabolites based on the full
> range of available science and data.  This workgroup is composed of
> scientists from the USAF and EPA, with technical expertise from TERA 
> and
> scientists such as Dr. Fisher and Mr. Clewell under contract to the
> USAF.  The results of this joint USAF-EPA workgroup will serve as
> important input to ongoing TCE risk assessment activities, including a
> planned multi-agency consultation with the National Academy of Sciences
> on TCE science issues as well as EPA's revised TCE human health risk
> assessment.  No conclusions as to the human health risks of TCE 
> exposure
> are being developed as part of this project; and no judgments as to 
> what
> should or should not be used in risk assessment are being made.
